Endiagram MCP

MCP server for EN Diagram - deterministic structural analysis powered by graph theory. Every result is backed by a named mathematical theorem. No AI inside the computation. Its 7 documented tools cluster into structure, invariant, live, reachable.

People connecting this server to Claude, Cursor, VS Code, or another MCP client. The project is written in JavaScript.

01 · Install Endiagram MCP

before you install - you'll need

The README does not document required environment variables for a basic install.

Claude Code

claude mcp add dushyant30suthar-endiagram-mcp --transport http https://api.endiagram.com/mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "dushyant30suthar-endiagram-mcp": {
      "url": "https://api.endiagram.com/mcp"
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions · remote - your agent's requests go to api.endiagram.com

endpoint auth accepted our unauthenticated MCP initialize - no credentials needed to connect

license MIT - declared in the repository

npm package @endiagram/mcp - the @endiagram scope differs from the repo owner (dushyant30suthar); confirm it's the project's official package

registry namespace io.github.dushyant30suthar is GitHub-verified and matches the repo owner

03 · What Endiagram MCP can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

An agent gets 7 documented tools across structure, invariant, live, including structure, invariant, live, reachable.

Capability map

Tools grouped from the project's README - what Endiagram MCP lets an agent do.

Structure

1 tool - e.g. What is this system? Shape, stages, bridges, cycles, critical path, dominator tree, min-cuts, subsystems, actors, locations.

structure

Invariant

1 tool - e.g. What's always true? Conservation laws, T-invariants (sustainable cycles), depletable sets, deficiency, reversibility.

invariant

Live

1 tool - e.g. Can it deadlock? Can entities overflow? Siphons, traps, unbounded cycles, structural liveness and boundedness.

live

Reachable

1 tool - e.g. Can X reach Y? Path, distance, boundary crossings. from/to accept entity or action names.

reachable

Equivalent

1 tool - e.g. Are two systems the same, or what changes if I change this one?

equivalent

Compose

1 tool - e.g. How do parts combine (merge) or how does a part stand alone (extract)?

compose

Render

1 tool - e.g. SVG or PNG diagram. Only call when the user asks to visualize.
